본 논문에서는 DF(Decode-and-Forward) 릴레이를 갖춘 다중 홉 OFDMA(Orthogonal Frequency Division Multiple Access) 방송 시스템에서 PF(Proportional Fair) 기반 부반송파 할당 문제를 고려합니다. 이 문제는 사용자 간의 비례적 공평성을 달성하고 홉 간의 독립적인 주파수 선택적 페이딩이 제공하는 다양성을 활용하려는 목적으로 혼합 이진 정수 프로그래밍 문제로 공식화되었습니다. 최적의 해를 찾는 것이 불가능하므로 두 가지 효율적인 휴리스틱 기법을 제안합니다. 시뮬레이션 결과는 동일한 공정성 성능으로 제안된 방식이 기존 PF 스케줄링 방법에 비해 상당한 용량 이득을 달성한다는 것을 나타냅니다.

Abstract: This paper considers the proportional fair (PF) based subcarrier allocation problem in a multihop orthogonal frequency division multiple access (OFDMA) broadcast system with decode-and-forward (DF) relays. The problem is formulated as a mixed binary integer programming problem with the objective to achieve proportional fairness among users and exploit the diversity provided by the independent frequency selective fading among hops. Since it is prohibitive to find the optimal solution, two efficient heuristic schemes are proposed. Simulation results indicate that with the same fairness performance, the proposed schemes achieve considerable capacity gain over the conventional PF scheduling method.
